Today I set a new PR of 248-7X. I'm using a TM1000 with JSB Monsters, first gen. The thing that bothers me is the 7X. Only 8 of the .177 holes were actually 10's before scoring with a gauge.
I feel like I've found the best pellet for this barrel, and I prep my pellets by weighing to 1/10th grain and careful inspection. Right now the gun is shooting 13.4 grains at 707 fps or 17.65 fpe. Would I notice anything by fiddling with the velocity in terms of trying to get the best speed to match the pellet? I think the gun performed a little better when I switched from the 13.5 grain JSBM's I used on my first target (240-6X) to the 13.4's for the PR target, essentially changing the velocity a little with a lighter pellet. If that is so, how in the world do you determine the best weight pellet and the best velocity to match it?
Thank You!
